Title: Connection part for metallic-pipe covered optical fiber and connecting method therefor
Inventor: HIRAMOTO YOSHIYUKI
IPC: G02B6/24
Filed: 1990-08-06
Abstract: PURPOSE:To prevent transmission characteristic from deteriorating and to secure high mechanical strength by previously performing diameter machining for part of an end part of a sleeve pipe which has an internal diameter matching the external diameter of a metallic pipe, connecting the optical fiber and then reducing the diameter of a remaining diameter-unreduced part by extension until its internal diameter equals the internal diameter of the metallic pipe, and welding the metallic pipe. CONSTITUTION:The diameter reduction machining the performed from a position which is 25mm away from one end to the sleeve pipe 3 to a position which is 50mm away, and parts of metallic pipes 2 and 2 from their terminal to positions which are 650mm away are cut and removed to expose optical fibers 1 and 1. The opposite side of reducer part 3A the pipe 3 is fitted onto the outer periphery of the end part of one pipe 2 and after the terminals of the optical fibers 1 and 1 are connected by fusion splicing and recoated with resin, the pipe 3 is drawn back from the state in Figure 2 to Figure 3 and welded to the metallic pipe 2. Then a half-split die 11 is fitted to the reducer part 3A and moved and the other end of the pipe 3 is reduced in diameter except part of it and welded. Thus, the pipes 2 and 3 become nearly equal in internal diameter and a connection part which has a discontinuous step part is formed.

Title: Smoke emitting apparatus
Inventor: KAWAI MITSUO
IPC: C06D3/00
Filed: 1993-07-30
Abstract: PURPOSE:To provide a smoke emitting apparatus from which smoke crawling on the floor and the ceiling can be obtained. CONSTITUTION:A vaporizer 2 provided with a heater 3 has a jetting outlet 4 at the tip part and a discharging system 10 consisting of a discharging electrode 11 and an earth electrode 12 is connected with a voltage elevating apparatus 14 to elevate voltage to the level sufficient to produce corona discharge.

Title: Magnetic recorder
Inventor: KITAZAWA KEIJI
IPC: G06F3/06
Filed: 1981-12-25
Abstract: PURPOSE:To suppress the continuous destruction of recording data which may be generated due to the malfunction or failure of a controlling device to its minimum: one sector, by incorporating a writing malfunction preventing control part in a disc controlling device. CONSTITUTION:When a writing signal 6 is on at the timing when a sector pulse 3 is turned on, the output terminal Q of an error detecting J-K flip-flop which is off in initial state is inverted and turned on. Said state is discriminated as malfunction and an output signal 13 from the output Q is fed back to the controlling device as a signal to start error processing. A writing signal 6 is turned off at a gate by an error discriminating output signal 13 independently of the error processing so as not to be outputted to a disc device 10. Even if the writing signal is turned off, the error processing of the controlling device is ended and the writing operation is not restarted until a clear signal 15 of the flip- flop 14 is turned on.

IPC: F02M9/14
Filed: 1984-10-05
Abstract: PURPOSE:To accelerate the atomization and carburetion of fuel, by using a rubber nozzle type amin throttle part, and forcibly atomizing the fuel fed to the narrowmost part, while taking in a part of suction air in time of high load and mixing it with a rich air-fuel mixture. CONSTITUTION:When an accelerator is operated, a throttle cone 12 goes up whereby a main throttle part 16 is opened and air is taken in. In time of low engine load, a throttle valve actuating lever 34 and a stopper lever 32 are in a noncontact state, and an auxiliary air throttle valve 21 is situated in a full- close position by dint of a return spring 33. Therefore, air is all taken in through the main throttle part 16, and a suction air quantity is controlled according to a passage sectional area of a narrowmost part 16a. In consequence, the fuel fed out of an injection valve 17 is forcily atomizable. On the other hand, when the accelerator is largely operated, a tip end of the stopper level 32 comes off an engaging pin 24 so that the throttle valve 21 is opened by a diaphragm valve gear 25, thus partial air is led into an engine through an auxiliary air passage 5.
